ABSTRACT:
A collapsible framework capable of being manipulated between a collapsed condition and an expanded, locked condition includes a plurality of legs and a plurality of collapsible quad sections. The legs are disposed generally in parallel with one another and in a bundle when the framework is in the collapsed condition. Each quad section includes two split step scissor units and two step scissor units. Each split step scissor unit is joined at one end to a respective leg, and including two arms that are pivotally joined, at least one of the arms being telescopic and including means for locking the arm at a predetermined length. Each step scissor unit is joined at one end to the other end of a respective split step scissor and at its other end to the other step scissor unit, and each step scissor unit includes two arms that are pivotally joined, at least one of the arms being telescopic and including means for locking the arm at a second predetermined length. The framework may further include a flexible canopy supported by the legs and quad sections, or may further include a plurality of tension cables joining ends of the legs and scissor units. Other types of quad sections are also disclosed.
